Simple Plot: Simple is a free interactive, mathematical app for any Android tablet. This app is great for individual student work or student collaboration. The app allows for data analysis and can produce a linear regression model. It allows students to plot (x, y) points and graph a function. Students can specify the axis' title for either the "x" axis and the "y" axis. Students can enter the "x" values and the "y" values right in the table. The graph develops directly below the table as the students enter the values.
When the students have their graph, they can personalize the graph with options to the right. They can deem it linear or allow the curve and choose a scatter plot or produce a line. There is an option to show the grid on the graph. Students can save the graph and export it to a report. They can also share it with other students or groups in the classroom. This is a great tool for students to create a quick graph, see a trend, and make predictions over time.
Benefits of Tool or App
It is a FREE app on any Android tablet.
User friendly.
Students can specify axis' title right in the table.
Easy to enter values. Has it's own number pad for entering values.
If there is a missing or invalid value in a column, the column will be ignored
The graph develops directly below the table as the students enter the values.
The user can move the graph from left and right, up and down, and maximize and minimize the view of the graph. This can give the user multiple views of the model.
There are options which allows the students to customize the graph and specify whether to graph the function, set up a linear regression model, set up a scatter plot, graph a line, and use grid lines.
Will produce the linear regression equation to show the change in rate over time.
Can export the graph with the "Save Graph" button. Graphs save to the Simple Plot folder in the tablet memory.
Great for individual or collaborated student use.
Constraints of Tool or App
The app is limited to Android Tablets. It is not available for smart phones.
The options are limited. Unable to specify the type of graph unique to the situation.
Unable to place a title for the graph.
Unable to plot more than one trend. Cannot compare two or more trends. No side-by-side comparison.
Unable to enter a function equation, can only enter "x" and "y" values.
Unable to show function equation once values are entered. Only for linear regression model.
Line of best fit does not extend beyond final point. Makes a little difficult to make predictions.
Has no instructions or help section.
How To Use Tool or App
Once the app has been activated, students can "touch" on the section to enter a title for either the x-axis or the y-axis. The labels will automatically display on the graph. Students enter the "x" and "y" values directly into the table using the given key pad. Students can manipulate the type of graph they are plotting over to the right. They can choose to plot the function as the points are being entered, set up a linear regression model, and use grid lines on the graph. Students can save the graph to export for a report.

Students activate the app and see this screen. They can enter the TITLES of the x-axis and y-axis in the space provided as seen below:
Once students have chosen the titles they can enter the values for x (Year) and y (Population). The graph will develop as they enter the values:
Depending on the type of graph the students need to produce they can customize the graph with the options to the right of the graph. The students can keep the graph as a function and watch the trend or create a linear regression model to make predictions and see the line of best fit equation.
In the upper right corner, students can save the graph to the tablet to export if needed. Students can enlarge the graph, move it side to side or up and down to get multiple views. Students can also create a picture of just the graph:
Classroom Uses for Tool or App
Student Uses
Students can use as an investigation tool. They can enter data to discover the type of graph that is produced.
Students can collect data to produce a linear regression model.
Students can make predictions over time from the data.
Students can discover the linear regression equation of the line of best fit and see the rate of change.
Students can analyze given data within the classes and make class conjectures about the data. (class discussion)
Students can use this app in other classes other than math, such as science (chemistry, physics, biology), business class, and P E to analyze their trends over time with exercise. (heart rate, number of laps, sit-ups, push-ups, etc, and weight lifting)
Teacher Uses
Teachers can use as a tool to create graphs ahead of time to give to students to analyze as a warm-up, during class, for a test or quiz, or as homework.
Teachers can take a screen shot of data and/or graph to create classroom discussion on the data and make suggestions of what the data could be relating to.
Teachers can use to demonstrate how to create the graphs, analyze the data, and customize the graphs.
Teachers can use to show a specific student how he/she is trending in class with their grades.
Teachers can use in a meeting (PLC) to discuss statistics about their scores or going over an assessment.
